A Smashing Time

Why is it that some people seem to go out of their way to run over objects in the road that have obviously been accidentally dropped by someone else? Just the other day I saw several pieces of Tupperware in the road that someone had dropped. Most of the people went around or straddled it with their car. Most, not all. There were a couple of cars who decided that it would be a good idea to flatten it. Is it bad that when I see someone about to intentionally run over something, I start hoping that what they are about to run over is really just cleverly designed spike strips designed to catch those heartless fools?
